Select Winners

Daily winners-selection routine. Waits on MAG's forecast_all_symbols to have a COMPLETED_OK since the last NYSE market close, fetches MAG's latest full forecast report and SAP's sentiment report for the same entry_date via ORK proxies, applies the sentiment veto (drop any candidate with SAP score ≤ 0.15, the AlphaVantage Somewhat-Bullish floor), sorts the remaining candidates by absolute magnitude, runs the confidence cull with fallback (filter by magnitude accuracy ≥ minimum_confidence_threshold; on undershoot, fall back to the unfiltered top max_winners), and writes the winners file at winners_storage_dir/<entry_date>.txt. The tuning knobs (sentiment_upper_limit, minimum_confidence_threshold, max_winners) are persisted on WIN's ini and apply to every run. Default concurrency-gate setting (off) holds the system exclusive while the routine runs.
